With plenty of dog food on the market, you have many options for foods made with high-quality ingredients and limited fillers. However, dogs can still develop an allergy or intolerance to many of these ingredients.
Doctors said, some environmental allergies can cause skin and gastrointestinal problems in dogs, and certain foods can also trigger allergies. Depending on your dog’s symptoms, they may have either an intolerance or an allergy to one or more ingredients in their diet.
Continue reading to discover seven common allergens in dog food and how to determine if your pup’s food is causing an allergic reaction.
Is It an Allergy or an Intolerance?
First off, understanding the difference between a food intolerance and a true food allergy is crucial.
Food intolerance means your dog struggles to digest a certain ingredient, such as dairy, and this does not trigger an immune system response.
Conversely, a food allergy occurs when your dog’s immune system incorrectly identifies a specific food ingredient (usually the protein source) as dangerous. The body reacts by producing defensive antibodies to combat the perceived threat (the ingredient).
“Food allergies in dogs are typically managed rather than cured,” Dr. Kong explains. “Once an allergen is identified, the best strategy is to avoid it. This often involves switching to hypoallergenic or limited ingredient diets. Regular check-ups and monitoring are essential to ensure the allergen remains out of the dog’s diet.”
She also mentions that it’s common for dogs with one food allergy to develop sensitivities to other ingredients over time. Therefore, it’s important to closely monitor any new symptoms and modify their diet as needed.
Major Signs of a Food Allergy in Dogs
If your dog has a food allergy, you might observe the following symptoms:
- Sneezing
- Frequent scratching due to itchiness, especially around their paws
- Hot spots, which are skin infections resulting from excessive scratching
- Skin rashes
- Scaly or oily skin
- Pigmented skin
- Leathery texture of the skin
- Eye discharge
- Red eyes
- Vomiting and diarrhea
- Hair loss
- Ear infections
- Secondary yeast or bacterial infections (pyoderma) of the skin or ears
Most Common Food Allergies in Dogs
Dogs can develop an allergy to various foods, but some triggers are more common than others:
- Beef: Often a staple in dog diets, beef is one of the most common food allergens. Feeding your dog beef for years can increase their chances of developing an allergy or intolerance due to prolonged exposure.
- Dairy: While some dogs have difficulty digesting lactose (lactose intolerance), leading to gas, diarrhea, and vomiting, a true dairy allergy can also cause these symptoms along with skin itchiness and other related issues.
- Wheat: Although allergies to meat are more common in dogs, wheat can still be a significant allergen. Dogs with a wheat allergy may benefit from grain-free diets, so it’s important to consult with your vet.
- Eggs: Dogs with an egg allergy react negatively to the proteins in egg yolk. While many dog foods contain eggs, careful label reading is essential to avoid them.
- Chicken: Similar to beef, chicken is prevalent in dog foods. Dogs that eat primarily chicken-based foods may develop an allergy or intolerance over time.
- Lamb: Lamb is often recommended for dogs allergic to beef or chicken. However, it can also be an allergen, causing intolerance or allergic reactions in some dogs.
- Soy: Some earlier studies suggest that soy can cause health issues, including allergies, reproductive and growth problems, thyroid dysfunctions, and liver disease in dogs, although conclusive results are still pending.
Other less common but potential allergens include pork, rabbit, and fish.
Are Some Breeds More Likely to Have Food Allergies?
While any dog can develop a food allergy, certain breeds appear more susceptible. Dr. Kong notes, “Labrador Retrievers, Cocker Spaniels, and German Shepherds are among the breeds I often see with food allergies.” However, she emphasizes that this is not solely a breed-specific issue.
According to Dr. Kong, genetics play a significant role in the likelihood of a dog developing allergies. If a dog’s immediate family members, like their parents or siblings, have food allergies, the dog is at a higher risk, regardless of breed. Thus, a dog’s genetic lineage is equally, if not more, crucial in determining their susceptibility to food allergies.
How to Identify Your Dog’s Food Allergy
If you suspect your dog might have a food allergy, the first step is to consult your vet to pinpoint the allergen. Your vet may suggest skin and blood allergy tests or recommend an elimination diet.
This diet involves removing potential trigger ingredients, such as beef, from your dog’s diet for six to eight weeks and replacing them with a different food source. If your dog shows no allergy signs on the new diet, you’ve successfully identified the allergen. If symptoms persist, the process repeats until the trigger is found.
How to Treat Food Allergies in Dogs
Treating a dog’s food allergy primarily involves avoiding the allergen. If the allergy is to a single ingredient, switching to an alternative dog food may resolve the issue. However, for dogs with multiple food allergies, your vet might recommend a prescription diet or suggest trying a raw food or limited ingredient diet.
Another option is choosing dog foods with hydrolyzed proteins, where the protein is broken down molecularly to eliminate the presence of allergens.
For those interested in homemade solutions, there are many homemade dog food hacks and healthy recipes. However, it’s crucial to consult your vet before preparing homemade food to ensure it meets your pet’s nutritional needs.
Conclusion
Food allergies in dogs can significantly affect their quality of life, but with careful management and the right dietary adjustments, these challenges can be effectively handled. Understanding the symptoms and potential triggers of food allergies is crucial for timely and effective treatment. If you suspect your dog has a food allergy, it’s essential to consult with a veterinarian who can guide you through the process of diagnosis and treatment. By identifying the specific allergens and adjusting your dog’s diet accordingly, you can help alleviate their symptoms and improve their overall well-being. Remember, each dog is unique, and what works for one may not work for another; hence, personalized care and regular veterinary check-ups are key to successfully managing food allergies in dogs.
Frequently Asked Questions About Food Allergies in Dogs
What breeds are most commonly affected by food allergies?
Labrador Retrievers, Cocker Spaniels, and German Shepherds are frequently observed to have food allergies. However, any breed can develop food allergies, emphasizing that genetics and family history are crucial factors.
How can I tell if my dog has a food allergy?
Common symptoms of food allergies in dogs include itching, skin rashes, gastrointestinal problems like vomiting and diarrhea, and chronic infections such as ear or skin infections. If you notice these signs, consult your veterinarian for proper diagnosis and testing.
What is the process for identifying a food allergen in my dog’s diet?
The most effective method is an elimination diet, which involves removing suspected allergens from your dog’s diet and replacing them with alternatives for six to eight weeks. If symptoms improve, the removed ingredient may be the allergen. The process may need to be repeated to pinpoint the exact trigger.

Avoiding the allergen is the primary treatment method. Depending on the severity and the number of allergies, your vet might suggest specific diets, such as hypoallergenic, limited ingredient, or prescription diets. In cases where standard options are insufficient, hydrolyzed protein diets or homemade food (under veterinary supervision) might be recommended.
